智能電網(wǎng)云存儲訪問控制中用戶屬性更新撤銷方法研究
[Abstract]:With the rapid development of smart grid technology, the emergence of power big data will make the power system data and information explosive growth. In the face of massive, distributed and heterogeneous information, the existing power system data storage platform is difficult to meet the storage requirements of smart grid information. Cloud storage system has great advantages in storing and sharing massive data, but it also brings hidden trouble to data security in smart grid cloud storage system. Therefore, ensuring the security of data becomes an urgent problem in smart grid cloud storage system. Access control technology can prevent unauthorized users from accessing system resources and ensure the security of data. Access control based on attributes can realize complex and fine-grained access control by setting access policy reasonably. It can be used in smart grid cloud storage system. However, in the practical application of attribute-based access control, user attribute update revocation is an inevitable problem. In order to solve this problem, this paper deeply studies the attribute-based access control model in smart grid cloud storage system, and designs a user attribute update revocation method. The following works have been accomplished: (1) aiming at the problem of updating and revocation of user attributes in attribute-based access control, the encryption algorithm based on ciphertext attributes and the scheme of user revocation based on attributes are combined and improved. A user attribute update revocation algorithm is designed, the security of the algorithm is analyzed theoretically, and the efficiency of user attribute updating is improved. (2) aiming at the problem of user attribute update revocation in smart grid, This paper presents an access control model for multiple authorization centers in smart grid cloud storage systems, and applies the user attribute update revocation algorithm proposed in this paper to smart grid cloud storage systems. The efficiency of private key updating is improved. (3) the Spark cloud storage platform with nine nodes is built using laboratory equipment, and the execution efficiency of user attribute updating method is tested by using the historical data of a power supply bureau. Compared with the traditional method, the proposed method can significantly improve the execution time of user attribute update revocation.
